Immortale Dei §22

²² A similar state of things would certainly have continued had the agreement of the two powers been lasting. More important results even might have been justly looked for, had obedience waited upon the authority, teaching, and counsels of the Church, and had this submission been specially marked by greater and more unswerving loyalty. For that should be regarded in the light of an ever-changeless law which No of Chartres wrote to Pope Paschal II: "When kingdom and priesthood are at one, in complete accord, the world is well ruled, and the Church flourishes, and brings forth abundant fruit. But when they are at variance, not only smaller interests prosper not, but even things of greatest moment fall into deplorable decay."(21)
